What researchers measure

Primary outcomes

  1. Percentage of Participants Who Were Composite Responders Based on Improvements From Baseline in Daily Worst Abdominal Pain And Daily Stool Consistency Scores

    Composite responders were defined as a participant who met the daily response criteria for at least 50% of the days with diary entries during the interval of interest. A participant must had met both of the following criteria on a given day to be a daily responder: 1) Daily pain response: worst abdominal pain scores in the past 24 hours improved by ≥30% compared to baseline (average of daily worst abdominal pain the week prior to randomization). 2) Daily stool consistency response: Bristol Stool Scale (BSS) score \<5 (ie, score of 1, 2, 3, or 4) or the absence of a bowel movement if accompanied by ≥30% improvement in worst abdominal pain compared to baseline pain. Bristol stool scale was defined as 7-point Scale in which a score of 1 = separate hard lumps, 2 = sausage shaped but lumpy, 3 = sausage-like with cracks on the surface, 4 = sausage-like but smooth and soft, 5 = soft blobs with clear cut edges, 6 = fluffy pieces with ragged edges, and 7 = watery with no solid pieces.

    IBS-QoL responders were defined as participants who achieved at least a 14-point improvement in IBS-QoL total score from baseline to the applicable visit. The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100-point (0= worst; 100=better) scale for ease of interpretation.

    The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100- point scale (0=worst; 100=better) for ease of interpretation.

  14. Change From Baseline in IBS-QoL Total Scores

    The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100- point scale (0=worst; 100=better) for ease of interpretation.

SecondaryIBS-QoL Total Scores

The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100- point scale (0=worst; 100=better) for ease of interpretation.

SecondaryChange From Baseline in IBS-QoL Total Scores

The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100- point scale (0=worst; 100=better) for ease of interpretation. A positive change from Baseline indicates that quality of life improved.
